Problema Solution
A fish tank has a length of 60 centimeters and a width of 31.5 centimeters. The water height in the fish tank is 28 centimeters. A fish swims from a bottom corner of the tank up along a diagonal path towards the surface of the water until it reaches the opposite face of the tank. Find the distance that the fish swam.
Answer provided by our tutors
let
d = the length of the diagonal that is the distance the fish swam
using the Pythagorean Theorem we can write:
d^2 = 60^2 + 31.5^2 + 28^2
by solving we find:
d = 73.32 cm
